The embodiment of the invention discloses a kind of means for anti-jamming and method of bimodulus electronic equipment, to ensure on the basis not affecting the proper communication of second communication pattern, prevent the sensitivity of the clutter interference second communication pattern outside the first communication pattern working frequency range.
See Fig. 1, show the structural representation of a means for anti-jamming embodiment of a kind of bimodulus electronic equipment of the present invention, the means for anti-jamming of the embodiment of the present invention can be applied in bimodulus electronic equipment, and bimodulus electronic equipment can be the electronic equipments such as mobile phone, notebook, panel computer.
The means for anti-jamming of the bimodulus electronic equipment of the present embodiment can comprise: first communications module 100 corresponding with the first communication pattern and the second communication module 200 corresponding with second communication pattern;
Wherein, the first communication pattern and second communication pattern are two kinds of different network communication mode, and the first communication pattern works in the first frequency range, second communication work pattern in the second frequency range, and the low-limit frequency of the first frequency range is higher than the highest frequency of the second frequency range.
It should be noted that, when the working frequency range of the first communication pattern and second communication pattern working frequency range comparatively close to time, spuious meeting outside the working frequency range of the first communication pattern drops in the working frequency range of second communication pattern, thus affect the sensitivity of second communication pattern, such as, first communication pattern is gsm communication pattern, second communication pattern is cdma communication pattern, so, the working frequency range of the first communication pattern is the first frequency range, the working frequency range of second communication pattern is the second frequency range, wherein, the low-limit frequency of the working frequency range of gsm communication pattern is higher than the highest frequency of the working frequency range of cdma communication pattern.
In actual applications, China Mobile and CHINAUNICOM all use gsm communication pattern, and China Telecom uses cdma communication pattern; Wherein, the working frequency range of gsm communication pattern is generally divided into transmit frequency band and receives frequency range, and the working frequency range of cdma communication pattern is generally also divided into transmit frequency band and receives frequency range, concrete:
China Mobile uses the transmit frequency band of gsm communication pattern to be 885MHz ~ 909MHz, and reception frequency range is 930MHz ~ 954MHz;
CHINAUNICOM uses the transmit frequency band of gsm communication pattern to be 909MHz ~ 915MHz, and reception frequency range is 954MHz ~ 960MHz;
China Telecom uses 7 frequencies, is respectively Ch37, Ch78, Ch119, Ch160, Ch201, Ch242, Ch283, concrete, and transmit frequency band is 826.11MHz ~ 833.49MHz, and reception frequency range is 871.11MHz-878.49MHz.
As can be seen here, the low-limit frequency of the transmit frequency band of gsm communication pattern is 885MHZ, the highest frequency of the reception frequency range of cdma communication pattern is 878.49MHz, that is, the transmit frequency band of gsm communication pattern and the reception frequency range of cdma communication pattern only have the frequency interval of general 6MHz, namely, the transmit frequency band of gsm communication pattern is the first frequency range of the first communication pattern, the reception frequency range of cdma communication pattern is the second frequency range of second communication pattern, spuious outside the transmit frequency band of gsm communication pattern, namely, signal lower than transmit frequency band (the first frequency range) can drop in the reception frequency range (the second frequency range) of cdma communication pattern, thus affect the proper communication of CDMA.
It should be noted that, gsm communication pattern and cdma communication pattern are only a specific embodiment of the first communication pattern and second communication pattern respectively, first communication pattern and second communication pattern can also be other communication pattern, specifically not to limit at this.
Wherein, the concrete structure schematic diagram of the first communications module 100 can see Fig. 2, and the first communications module comprises: transceiver 101, power amplifier 102, duplexer 103, antenna 104 and the first filtration module 105, wherein:

Wherein, transceiver can select respective link to communicate according to the frequency characteristic of signal, duplexer can be switched on corresponding link, thus signal is transmitted by antenna, when the first communication pattern works in the first frequency range, transceiver can be communicated by low frequency filtering link, and then the first filtration module be arranged on low frequency filtering link can attenuate the signal lower than the first frequency range, to prevent the signal lower than the first frequency range from dropping in the second frequency range of second communication pattern, affect the sensitivity of second communication pattern.
The embodiment of the present invention, by the low frequency filtering link between power amplifier and duplexer arranges the first filtration module, this first filtration module can be decayed lower than the signal of the first frequency range, make when the first communication pattern is in working time slot, the receiver of second communication pattern need not be closed, ensure that on the basis not affecting the proper communication of second communication pattern, prevent the sensitivity of the clutter interference second communication pattern outside the first communication pattern working frequency range.

Pre-detection obtains spuious outside transmit frequency band of gsm communication work pattern and is generally-60dBm, and the signal frequency namely lower than the first frequency range is-60dBm, and the isolation of gsm communication pattern and cdma communication pattern is-10dB; Pre-detection obtains the sensitivity of cdma communication pattern receive signal for-104dBm, when signal quality parameter Ec/Io reaches-12dB, bimodulus electronic equipment can ensure proper communication, can calculate default amplitude thus for (-60-10)-(-104+12)=22dB.
